. Application filed SeptemberrSO, 1902. Serial No. 125,359. (Ne specimens.)

Be it known that:.we,HUGo KARLE, residing at Seckenheim, near'` Mannheim, and J EAN tially, of the carriers or dogs 1'6, of the lever SCHMIDT, residing at Mannheim, Germany,

have invented certain -new and useful `.]m i provements in Production of Substances Re-w sembling Leather, of which the following' is a f i l isms are driven from a central shaft 21.

The impregnatingliquid, which is contained in a. trough 2, is prepared as follows: First,

specification.

The present invention relates to a process i for the production of substances resembling' leather.

' 'The process eonsists,substantially, in passing a ieece through 'an impregnating liquid, squeezing same out by means of pressing-rolls, passing it through a drying-stove, pouring y j again liquid on same, placing it on plates,

passing it into a drying-chamber, and then Y dyeing, dressing, or otherwise treating or tinishing same.

The accompanying drawings illustrate an apparatusy which may process.

In the drawings, Figure 1 is a longitudinal be employed for this vertical section throughthe entire apparatus,

and Fig. 2 isa detail reciprocating device.

On a frame 1 there 1s arranged a trough 2 plan of the reversing or for the impregnating liquid. Into this trough there dips a roller 3, and under this roller .there passes'a sieve-like metal web 4C, which runs over several guide-pulleys. This metal Y web 4 runs between the two pressing-rolls 5 and then on througha drying-chamber 6, 'fwhich is provided with a heating-coil 7 and @with a pipe 8 for drawing off the vapors that are generated. Between the guiding-web 4 and the guide-roller 3 there is passed' a strip of fleece 9, which unwinds from the roller 23. 'lhisstrip 9 is composed of two layers of Wadding, whose fibers are situated at right angles to one anotheiz The fieece 9 is ledover a 'guiding-pulleyv 1i0 and is laid upon the sievelike frames 11. rlhese frames 11 have the four different characteristic positions 11iL 11 11" 11"'. Above the frame 1 there is further arranged a sprinkling-drum 12, which is provided with a sieve-like outlet 13, that can be Closed by means of any suitable slide or valveI 14. In thelower part of the frame lV there is arranged a conveyer-web15 fdr the frames lland a feeding' device for changing the frames. The feedmg devlce consists, substan- 17, which is pivoted on a pin 22`of the roller 18, and of the stud 19, which works in a groove in the roller 18. All the variou'smechanninety-seven per cent. poppy oil, to which three percent. white-burnt vitriol is added, is Vboiled in a vessel fitted with a stirring device; second, eighty per cent. astraehan fibrin glue, ten per cent. iish-oihtwo per cent. extract of leather-lye, two per cent, potash,and six per cent. camphor are boiled together. 'l-hese two boilings are mixed together in equal -quantitiesthat is, iifty per cent.4 of each boilingt scHMiDi, or MANNHEIM, f

and are diluted with hot Wate'rto from eighty i to ninety per cent. i

flhe binding medium in thesprinkling-drum 12, with which the iieeces are to be saturated, is prepared as follows: Raw caoutchoucwhich has been swelled, rolled, washed, cleaned, and dried is caused to completely swell up in a. small quantity of naphtha, and it is diluted with benzol or benzin until it has become liquid. From forty-nine to fifty-two kilo? grams of the benzin or benzol are employed to one kilogram of caoutchouc, according -to the speciiic gravity of the benzin or benzol'. To the dilute caoutchouc there may now be added Withadvantage a solution of i Borneo mort and resin in such proportions that the mixture in the sprinkling-drum consists of one-third Borneo morti, one-third dissolved caoutchouc, and one-third resin. y

The procedure in carrying out the process and employing the apparat-us is now as followsz'- All the mechanisms having been' set in motion by means of the central shaft 21, the iieece strip 9 is passed, by means of the sieve like metal web 4 and of the guide-roller 3,

through the impregnation liquid which is contained in the trough 2. From the liquid the iieece strip 9 "then passes through the two pressing-rollers 5, ywhich squeeze the liquid out of it as eifectually as possible. Thence main shaft 21.

the metal.

web 4f conveys the fleece strip through the drying-chamber 6, in which the moisture still present in the fleece is evaporatedl by the action of the heating-coil 7 the vapors of said moisture escaping then through the exit-pipe 8. The fleece strip 9 then passes 11 now moves farther on and arrives finally in the position 11". In the meantime the roller 18 has now rotated to-an extent such that the inclined portion of' its groove 2() begins to force the stud 19 of' thelever 17 to one side.

y the same This Ihas the result of causing the carrier or dog 1.6, situated in the left-hand portion of' Fig. 2, to move theadvanced f'rarne 11 out of' the position 11l into the position 11" and at time to push a fresh frame 11 out of' the position 11' into the position 11, lmmediately afterward the groove 20 then moves the lever 17, and consequently also the two dogs16,-back again into their original positions. f The frame, (which has been moved into the position 11"',) together with the fleece strip 9 lying upon it, is now moved by means of a hoist into a drying-chamber, and it is then dyedwith dyes which are dissolved inthe moistening liquid, and it is passed through design-rollers, dressed, or otherwise ornamented and finished.

degree of' moistening of' the fleece' is prepared by mixing 4solution of caoutchouc,

What we claim, and desire to secure by Letters Fatent of the United States, .is- Y Lift process for the production of material rese bling leather, consisting of first `impregnating fibrous substances with a liquid which is prepared by mixing a decoction of poppyoil and white-burnt vitriol with a decoction of fibrin-glue fish-oil, extract of leather, potash and-camphor, diluted with hot water up to eighty or ninety the excess of liquid from the fibrous material, then drying the same, then mixing it with a solution of caoutchouc resin solution such as linseed-oil or resin solution, then subjecting the fibrous material to a' final drying process and finally finishing or dressing it, substantially as described.

2. A process for the production of material resembling leather, consisting of first impregnating fibrous substances with aliquid which a decoction of poppyoil and white-burnt v iltriol with adecoction of fibrin-glue, fish-oil, extract of leather, potash and cam'phor, diluted with hot water up to eighty or ninety per cent. then' removingr the excess of' liquid fro the fibrous material, then drying the same, then mixing it with a thickening same with Borneo mort and resin, then subjecting the fibrous material to a final drying process and finally finishing or dressing it, substantially as described.
